This tool will allow you to verify a DigiStamp timestamp that you have in the form of a .p7s file. If you do not supply
the file that was protected then the verify function will display the "Protected Hash Value" for you to manually compare with your file's hash that you calculate
using an alternate method.
Privacy Note: Only your timestamp, containing your file's hash
and the TSA's signature, will be transmitted to DigiStamp. Your protected data file is not transmitted to DigiStamp.
If you have exactly one file and one timestamp, this tool will assume they correspond to each other.
If you wish to authenticate multiple files with their timestamps, the files must have the exact same name; aside from the .p7s extension of the timestamp.

This tool will allow you to hash your files and create
for them. You will need to save the timestamps that will be
returned to you in the form of .p7s files.
Privacy Note: The name of your file and its hash value will be transmitted to us when you create a timestamp using this tool. The contents of your file will not be transmitted to us and we do not keep your file's name. We will store hash values you send to us.
You will end this process with 2 files: your protected content (MyFile.doc) and a trusted
You must keep unaltered copies of both files; they are only evidence together:
This test requires you to download 12 small files with a total size of 11.4 MB. After downloading these files you will provide them to the web application using the file inputs seen above. Press the button to begin:
Click here if you had trouble downloading the files.
Since the easy download button didn't work we'll need you to download the files manually:
Great! The test is underway and results will be ready soon. After the test is completed you should delete the test files you downloaded, having multiple copies of the test files in your downloads folder can prevent the test from working in the future.
With this simple tool you are responsible for calculating your document digest through some independent
means of your choosing (search for tools). Then,
enter that digest value below, press Create
Time Stamp and the DigiStamp server returns your time stamp
which you must then save on your computer.
